I haven't changed my diet at all since becoming pregnant. I still eat/drink whatever I want and my LO is growing fine and doing great. I probably drink 1-3 20oz bottles of soda a day

. The only thing I would change is drinking more milk I think. I hate the taste of milk, but I need the calcium. I am starting to get tooth aches, and people say thats why (also because I dont take my vitamins).
My BP is always great, my LO is growing great and appears perfectly healthy, doc says my weight gain is fine, and my sugar tests even came back normal; I'm not too worried about it.
